Internet Sharing cutting off my internet?

[lordofuo]

I use internet sharing on my Mac Mini so I can surf on my MBP.

I notice that if I try to upload or download files for too long, my internet will completely disconnect for both computers. I have to reset my aircard on the Mini to get it working again.

This also happens if you are watching YouTube vids, and the file size is relatively large.

What is weird is, if I turn airport off on my MBP, and try the same thing JUST on the Mac Mini, the internet can stay connected all day.

What seems to be the problem? Is this a flaw in OSX internet sharing? Or in one of the computer's Airport?

Or possibly in my Aircard? (But why would it completely disconnect just because two computers are sharing the same connection?)

By the way, I have Alltel wireless. The card is old, but if I upgrade to the Verizon card, they will limit my bandwidth.

I hate living out in the middle of nowhere.

I know there aren't many, if any, ITs here, but still, any suggestions?

Comments, thoughts, or criticisms?
